Excited to share our preprint on sequencing extracellular/cellular rRNA to determine lysis in ~17k prokaryotic taxa, led by @kevinzhong2006. Rare taxa show high lysis, consistent with "kill-the-winner". Would love your comments biorxiv.org/content/10.1101/….

Excited to share our new manuscript out in @Ecology_Letters, in collaboration with @weitz_group, @inria_sophia, @phytopk at @SBRoscoff and @PiscoLov at @IMEV_mer. doi.org/10.1111/ele.13722

A thermal trade‐off between viral production and degradation drives virus‐phytoplankton population...

The impacts of temperature on viral infection of phytoplankton are not well understood. Here we coupled mathematical modelling with experimental data sets to explore the effect of temperature on...

Manuscript published today! Check out the method we used to isolate exocellular “free” DNA from the open ocean. Yes, nearly a THIRD of all the DNA in the ocean is nonliving! Available on LO Methods: aslopubs.onlinelibrary.wiley… How did it get there? Who is it coming from? Stay tuned!
